A New Method of Containment: IBM Nabla Containers
In the previous post about Containers and Cloud Security, I noted that most of the tenants of a Cloud Service Provider (CSP) could safely not worry about the Horizontal Attack Profile (HAP) and leave the CSP to manage the risk. However, there is a small category of jobs (mostly in the financial and allied industries) where the damage done by a Horizontal Breach of the container cannot be adequately compensated by contractual remedies. For these cases, a team at IBM research has been looking at ways of reducing the HAP with a view to making containers more secure than hypervisors. For the impatient, the full open source release of the Nabla Containers technology is here and here, but for the more patient, let me explain what we did and why. We’ll have a follow on post about the measurement methodology for the HAP and how we proved better containment than even hypervisor solutions.
[...]
Like most sandbox models, the Nabla containers approach is an alternative to namespacing for containment, but it still requires cgroups for resource management. The figures show that the containment HAP is actually better than that achieved with a hypervisor and the performance, while being marginally less than a namespaced container, is greater than that obtained by running a container inside a hypervisor. Thus we conclude that for tenants who have a real need for HAP reduction, this is a viable technology.

France’s cyber command marched in Paris’s Bastille Day Parade for the first time
For the first time, France’s military cyber command marched in this year’s Bastille Day parade on the Champs Elysees in Paris, alongside other units in the nation’s armed forces. The military noted that it’s a recognition of the advances that the unit has made since its formation last year, and reinforces that “cyber defense remains a national priority.”
French defense minister Jean-Yves Le Drian announced the formation of COMCYBER in December 2016, noting that the emergence of state actors operating in cyberspace was a new way to approach warfare. The command brought all of the nation’s soldiers focused on cyber defense under one command, with three main tasks: cyber intelligence, protection, and offense.
